AUSTRIA INTERCHANGEABLE PAID FOR BOOT HEELS Application filed June 21,1928, Serial No. 287,265, and in Germany January 30, 1928.

This invention relates to interchangeable pads for boot-heels which, bymeans of eyes or buttons, engage with indentations of the heel and aresecured in this position by a split-pin or similar finationaneans.

These known devices present the inconvenience that the eye or button isheld in the indentation of the heel only at one side by a spring, bentin U-shape. In other devices the heel-pad is fizz-ed in the heel bymeans of an eye and split-pin. These fixations otter no security for apermanent adhering of the heel-pad on the heel, as, owing to thesupporting on one side only, the button disen gages from theindentations and the straight split-pin or U-shaped spring getsdisengaged from the eye in consequence of the vibrations at walking, sothat the heel-pad drops off. The split-pin and spring might easily getlost at the interchanging, as it has to be en tirely removed.

These inconveniences are obviated, according to the invention, byguiding with friction the bent points of the split-pin in a sleeveembedded in the heel. This sleeve prevents detaching of the split-pinand ensures that the split-pins, when the pad is being fixed on theheel, spreads iurther asunder after having been inserted through the eyeso that the points hook over the eye, when the splitpin is being pulledback or, it a button is used, the points grip over the button from bothsides so that, even at vibrations, it cannot get detached and holdspermanently the heel-pad on the heel.

Two embodiments of the invention are illustrated, by way of example, inthe accompanying drawing, in which:

Fig. 1 is a plan-view of the heel with pad viewed from below.

Fig. 2 is a plan-view on the heel without the pad viewed from below.

Fig. 3 shows the pad in top-plan-vie-w.

Fig. 4c shows the fixation-device in operative position.

Fig. 5 shows in top-plan-view seen from below a heel with afixation-device of a11- other form of construction.

Fig. 6 shows the heel-pad for the heel- Fig. 5 in top-plan-view seenfrom below.

Fig. 7 shows in top-plan-view the heelpad-Fig. 6 fixed on the heel-Fig.5 seen from below.

Fig. 8 is a longitudinal section of Fig. 7 on larger scale.

Fig. 9 is a longitudinal section of Fig. 4.

a is the heel-pad oi rubber, Z) the heel of the boot, 0 the split-pinwith outwardly bent ends, 0 the guide-sleeve for the split-pin, ddesignates a slot in the heel designed to receive an eye m, fixed on theheel-pad a f are pins on the heel pad, are holes in the heel, designedto receive said pins f.

In Figs. 5 to 8 is g a button on the heel-pad and it a cavity in theheel designed to accommodate the button and the points of the split-pin10, embracing said button.

To fix a heel-pad a on a heel Z) the eye 6 or the button 9 is insertedinto the slot cl or cavity 6 respectively of the heel, whereupon thesplit-pin c is inserted so that the ends of its arms pass through theeye and project from the same, or grip around the button 9, so that thepoint oi the split-pin engages with the cavity 7L.

Owing to the outwardly bent ends of the split-pin 0 bearing against theguide-sleeve 0, when attempts are being made to pull out the split-pin,this pulling out is prevented. The points of the split-pin 0, onemerging from the guide sleeve 0 and the eye 6, tend to spread outwardlyowing to spring action and hook over the sides of the eye 6 so thataccidental detaching of the pad from the heel is prevented.

I claim:

An interchangeable heel-pad for bootheels comprising in combination witha heel having a cavity, a guide-sleeve extending from said cavity to theinner edge of the heel,

an eye. on the upper surface of the heel-pad designed to be insertedinto said cavity, and a split-pin the ends of the arms being bent inoutward directions said pin designed to be inserted through saidguide-sleeve in said heel and through said eye so that the outwardlybent points of the arms of the pin owing to their tendency to spreadhook over the sides of said eye.

In testimony whereof I affix my signature.
